Google has officially unveiled Google Play Game Services at its I/O 2013 developer conference today.
Google Play Game Services adds cloud saves, achievements and leaderboards for games on the Play Store.
The big news, however, is that the service is not only headed to Android and web, but also to the rival iOS platform, giving it a significant advantage over Apple's Game Center service.
Google Play Game Services also promises lag-free multiplayer, with several top Android game developers already said to be implementing the feature into their games.
An Android update for Google Play Game Services will be available immediately for all devices running version 2.2 (FroYo) and higher.
